The 23×115mm round is used in Soviet (USSR)/Russian/CIS aircraft autocannon. Although superseded by the 30×165mm round the Russian Air Force still uses it in the GSh-23L (in some aircraft's tail turrets and in the UPK-23-250 gun pod) and the GSh-6-23 (in the Su-24). This round still serves in many countries and is widely available. The projectile weight is 175 grams.

==History== The round was derived from the 14.5×114mm round by necking it out to 23 mm. The original rounds used a lower power charge of 33 g of sw 4/7 powder and achieved 690 m/s at a maximum pressure of 294.3 MPa. In 1954 an improved ammunition was introduced, featuring better projectile design and ballistic properties. The newer rounds have a powder charge to achieve 720 m/s.
